To all iii/0in t may concern Be it known that I, Guirr linnn'rznn, asubject of Villiam H, Emperor of Germany, residing at Akron, in thecounty of Summit and State of Ohio, havev invented new and usefulimprovements in Machines for insert.- ing fires in the Rini-EngagingPortion of Solid Tires, of which the following f is a specification.

This invention relates to machines for in-v serting cross-wires inthebase portion of solid tires and the primary objects of this inventionare to provide a machine capable of inserting cross-wires in avulcanized tire of annular formation, if desired, and designated toplace them at approximately any angle with respect to the longitudinalline of the tire. The mechanism for accomplish` ing these resultsembodies a rotary reciprocating drill for drilling the openings in thevulcanized tire, an inserting device for inserting the end of acontinuous wire in the opening formed by the drill; shearing mechanismfor shearing off the extending portion of the Wire; a hammer for furtherforcing the severed wire section into the tire; means for suitablysuppo-rting'an annular vulcanized tire in approximately any position tocause the placement of the wires at any preferred angle.

l/Vith the foregoing and other objects in vie-w', the invention consistsin the 'novel construction, combination and arrangement of partsconstituting the invention to ber hereinafter specifically described andillustrated inthe accompanying drawings which form a part h ereoi'wherein is shown the prey fer-red embodiment ofthe invention, butit isto be understood that changes, variations and modifications can beresorted to which p come within the scope of the matter herein# afterclaimed.

ln the drawings in which similar reference numerals indicate like partsin the different figures, Figure 1, is a View in side elevation of adevice embodying. this invention; Fig. 2, is a plan; Fig. 3, Vis adiagrammatic view of portions of the mechanism; Fig. ft, is an elevationlooking from the left in Fig. 1; and, Fig. 5, is a detail of a portionof the mechanism with parts thereof broken away to better illustrate theconstruction.

In detail, the invention embodies a frame 'coi-nprisingvlegs 1, 2, 3 andf1 arranged in pairs,,and the respective pairs connected at their upperportions by a member 5 forming a platform or supporting instrumentality.ll-lounted in suitable bearings in. the framework is arotatable shaftGsupported by a bracket 7 outside o f the pair of legs 1 and 2.liiounted on the, shaft G is a belt-receiviine,` pulley 8 by whichmotion is conununi ated to the shaft. The belt pulley 8 is preferablyconnected with one member of a clutch 9 operated by a bell-crank lever10 connected with a foot treadle 11 so that the rotation of the shaft (3may be controlled at will. Also mounted on the shaft G is a heavybalance ly-wheel l2. The shaft also bears a bevel gear 13 for a purposeto be later described. On the shaft (i is aspurpinion le adapted to meshwith a bevel-gear 15 on a counter shaft 16 also mounted in suitablebearings in the frame.

The mechanism for.feeding4 a wire continuously and progressivelyforward, step b v step, isas follows: Mounted in suitable slides 17 onthe upper member 5 of the frame is a gripping member 18 provided with anopening having a hardened steel plate or bushing 19 therein againstwhich. .the wire if; clamped when it is desired to vfeed the vwire tothe left in Fig. 1. The lower por# tion of the gripping member 18 isopen to provide a space Q0 (see Fig. 5) and extende ing across this faceis a pin 21 on which isinounted a cam 22 so fashioned that when swung inone position, (the left in Fig. 1) it will engage the wire 9.3 and forceit against the -harde-ucd bushing 19, thereby etl'ectually gripping it.The lower end of `the cam is provided with a pin 241 to receive thebifurcated upper end of an oscillating level; 25 the lower end of whichis fulcrumed on va pin 2G extending between the legssl and 1. The .leveris provided intermediate its ends with a; longitudinal slot 27 toreceive a pin on the vend of a link 28 the opposite end of which ispivot-ally connected with a lever :29 pivoted on a pin 3Q in a suitablebracket on the undenface of the member .5. The lower end of the lever 29is pivotally connected with a li-nk 31 which isv in turnpiifotallyattached to a pin 82 on one face of a cam fixedly mounted on the shaft16. It will be obvious that as the cam 33 is rotated an oscillatorymovement is communicated through the hereinbefore de scribed mechanismte the lever'li and as its first movement 'isl to the left in Fig. 3A

i oscillating is arranged 'to lie in thev path of the lug 36 y ro 'conical'opening 4 1" preferably provided with i From the foregoing seenthat as the' cam `it will rock the cam cani engages the wire and afterthis of brdinaryconstruction a tutes 'a guide for mechanis'mjto bedescribed later, and the upper end is provided with a hardenedbushingand constituting one which is provided vwith a knife and forcingpingmemberlS isa wire straightener 34 .embodyingthree rollers 3 5triangularly positioned between'wbch Vthewire passes 'for removing kinksand' bends, but as this is further descrip-j e lug 36 cam member33f`bears a projecting to be later described. Extending between the legs1 and 4 is a in 37 on which'v is mounted ave-rtically-4 lever 38'theright end of which 'and be depressed thereby-during the revolu# tion ofthe latter. The opposite end of the lever is normally depressed by afcoiled resilient element 39. Secured to the pin 37.v l

Abetweenthe legs 1 and 4 li`s an uprightmember 40 the lower portionofjfwhich .constimember ofv a shearing element for cutting on asection-of the wire as the wire is passed through the opening 41. due tothe movement 'of the gripping member 18. Slidably mounted on thefmember40 vis a' vertically reciprocating member 42 Vthe upper end of 43adapted toco-act with the bushing. The member 42 is causedto reciprocatevertically on the 'member 40 through the medium of a connecting rod 44which is pivotedeccentrically on the lever 38. description it will be33`revolves and the free end of the lever lug 3G encounters the 38 itcauses thelatter to swing downwardly thereby raising the opposite end ofthe lever the member 49'carrying the movable shear-member 43'upwardly,thereby severing the wire. n Extending to 'the left in Fig. y1 andsecured tothefleg 1 and 4 'is a frame 45 provided with a cut-.outportion to provide a recess 46 in which is mounted a verticallyadjustable shaft 47 on which is a turn-table 46. This vturn table bearspairs of alined arms 48. ,Between the members of each pair is a roller49 constituting Vsupporting' medium for a drum 50 having oneedge 5l,provided with ratchet-teeth for a purpose to be later described. Thehorizontal position of. the turn-table 46 is adjustable so that the drummay revolve at any angle with respect to the longitudinal line of thewire andin order toguide the drum I provide a pair of slides 52 andtothe upper face of the platform 5,v 'and' l61` secured iii position byl 'which is secured a needle or 53' adjustably secured provided withheads 54 and 55 respectivel capableof lbeing adjusted at approximatelyany desiredangle with respect to the drum and the tire mounted thereon.

In practice, a tire 56 usuallyy of annular formation, is placed on thedrum and held thereon in engagementwith the upper portion of theperiphery of the drum by a roller 57 held in place by an arm r58extending from "a `post 59 on the member 5 and capable of being raisedandslowered by a hand-wheel 60. In order to .hold the tire againstlateral thrust on one side the members 54 and 55 are provided. Theopposite l side lof the tire is held in position by means of a shiftableabutment means of a rod 62 secured to a standard 63 on the frame rl`hisabutment isprovided witha slotted opening 6 4 fora purpose lto belaterdescribed.

rEhe vmechanism for drilling an opening in the tire preparatory to theinsertion of the wire is accomplished by the following mechanism:Secured in a bearing 65 on the frame' and in a bearing 66 on the frame45 is a revoluble shaft 74 provided at one end with a beveledfpinion 67intermeshing with the bevel-gear 13 and receiving motion therefrom.Mounted in suitable bearings 68 and 69 on 4the frame is a shaft 70.rIhis shaft consisting of a plate 70 bears a sprocket-wheel 71 fromwhich a sprocket chain extends vto and around a sprocketavhcel 9801i theshaft 74 whereby the shaft 70 is revolved rlhe right end of the shaft 70is provided with a socket in drill .7 5. The needle passes through asuitable guiding opening yin the standard 63'when reciprocated bymechanism to be described and passes through the slot 64 and tire 56.The mechanism for reciprocating the shaft 70 and needle 7 5' comprises'a mounted at 7 7 on the frame 45 and connected at its outer end with anoscillating lever 78 the upperend of which is provided with slots 79 toreceive transverse pins 80 on a loose collar. 81 on'the shaft 7 O, asshown in Fig. .3 so asto permit both longitudinal reciprocation androtation of the needle 75. In order to rock the lever 78 there isprovided between the legs 2 and 3 a box or ways 82 in lwhich is adaptedto move reciprocally the head 83 of a rod 84 the opposite end 85 ofwhich is pivotally connected with a lever 7 8. In order to reciprocatethe rod 84 there is provided in one face of the cam 33 arace 86 in whichruns a pin 87 on one vface of the revolves, the shaft 70 land needle 75will be alternately reciprocated, driving a needle through the base orrim-engaging portion of the tire 56.

In order to accurately of the wires in the tire, the dru1n50 1s causedlink 76 pivotally space the position ies head 83 of the rod 84 and asthe cam 33 1,1 ieeoo to move intermittingly by the following mechanism.:Mounted on a bell-crank lever V88 on the frame 45 is a pawl 89 lWhichengages the ratchet-teeth in the edge of the drum '50. The opposite endof the bellcrank lever 88 is connected to a bent connecting rod 90 theopposite end of which is.

from the face of the tire in order to perform l .its functions, a shortpiece or end of Wire projects from theside of the tire after theshearing operation andin order to4 drive v these projecting ends -of theWire into the tire so as to bring these ends flush With the side facesof the tire, I provide the following mechanism: The lever 29, pivoted onthe pin 30 has an extension 93 projecting up- Wardly through theplatform 5. This extension 93 is provided at its upper end with a slot94a Slidably mounted in a suitable opening in the post 59 is a hammer 95provided With a head 96 having a laterally projecting pin Which engagesthe slot '94. The hammer 95 is adapted to move approximately.simultaneously with the gripping l member 18A but in' an oppositedirection thereto vand the 'post 59 provides a suitable guiding andsupporting member for the hammer. In practice, the hammer will beWithdrawn out of the path of the projecting end-of the Wire which hasjust been inserted in the tire and which has been severed from.

the continuous Wire 23 and the projecting Wire is brought by the paWlinto direct alinement With the hammer Which at its next reciprocationforces it into Ithe tire and with the ends thereof flush With the' sidefaces of the tire. Y

It is thought that/the operation of the ydevice Will be apparent fromthe description of the mechanism, but for accuracy it is thought that avshortfdescri-ption will be of .An annular. tire is positioned looselyon" termined and the drum adjusted by sh'fting assistance. v

thejdrum 50 and the angle at which it is desired toplace the Wires inthe tire is dethe' turn-table 46 vand the members 5 and 53. The abutmentplate 61 is then placed so as to engage the side of the tire and lockitin position. In practice, a tire will be usuallyconsiderably largerthan the drum, but the'upper-portion which engages the drum 'willbaiforcedvdownwardly into position by means of the roller 57., As themechanism operates the needle or drill is `reciprocated back and forthwhile being continuously rotated and after passing through the tire andas it starts on its return, the gripping member 18 will advance, forcing'the end of the Wire 23 into the opening madein the tire,` and as thegripping member reaches the 'end of its stroke, the shearing member 48is raised sufliciently to shear off the inserted piece, leaving aportion thereof projecting. As soon `as the shearing operation has takenplace the continuous upward movement of the free end of the lever r38which is controlled in its operation by the' lug 36, is raisedsufficiently to bring the pins into .engagement With the upper end ofthe slot 91, therebyl raising the bent connecting-rod 90 upwardly torock the bell-crank 88 causing the paWl 89 to force the drum forward afractional portion of a revolution. As has heretofore been described,the hamend of thevvire to beprcperly positioned, it is then forced intothe tire thereby. As soon as the position'of the drum has been shifted,the drill 75 will again perform its function on the portion of the tirein front of the slot 64,- in the abutment plate 61 and at the nextforward reciprocation ofthe gripping-member 18 a Wire is forced into theopening made by the needle, the hammer 96'Will force the projecting endofthe preceding Wire firmly to its place and Hush with the side faces ofthe tire.
